Hi,
The first story is not entirely correct. Several experiments with other (read cheaper) construction materials used in bullets and cases as well as the introduction of 9mm submachineguns meant that a cartridge, once 'built' for the Parabellum was used in a large number of guises and qualities and some measures were taken to improve reliability under changed circumstances.
Since we don't really have to shoot wartime quality 9mm ammo, this isn't a very big problem anymore. Sticking to a brand that follows the original 9mm specifications, like Sellier & Bellot or Winchester means reliable operation in most cases, especially as their OAL is very close to original specs.
A quality check on pistol and magazine springs is needed to assure correct functioning of the pistol.
My 1913 Dutch DWM, the 1937 S/42 and the VoPo all digest 115gr and 124gr S&B without much problems. Lost some small springs during the last few years, but that's normal wear.
Basically, if you don't want to break anything, don't shoot them. If you can live with the occasional (unnumbered) spring breakage then just shoot the S&B and Walmart. If you want custom performance, reload.
